Overview
This topic discusses the JSON representation of domain objects. Domains specify the set of valid values for a field.
The following domain objects are discussed:
- Range Domain
- Coded value domain
- Inherited domain
Range domain
Range domain specifies a range of valid values for a field. The type property for range domains is range.
{
"type": "range",
"name": "<domainName>",
"range": [ <minValue>, <maxValue> ]
}{
"type": "range",
"name": "Measured Length",
"range": [1,10000]
}Coded value domain
Coded value domain specifies an explicit set of valid values for a field. Each valid value is assigned a unique name. The type property for coded value domains is coded.
{
"type": "codedValue",
"name": "<domainName>",
"codedValues": [
{"name": "<codeName1>", "code": <code1>},
{"name": "<codeName2>", "code": <code2> }
]
}{
"type": "codedValue",
"name": "Material",
"codedValues": [
{
"name": "Aluminum",
"code": "AL"
},
{
"name": "Copper",
"code": "CU"
},
{
"name": "Steel",
"code": "STEL"
},
{
"name": "Not Applicable",
"code": "NA"
}
]
}Inherited domain
Inherited domains apply to domains on subtypes. It implies that the domain for a field at the subtype level is the same as the domain for the field at the layer level.
{
"type": "inherited"
}{
"type": "inherited"
